Board approves Martin Marietta request to install warning signs and solar beacons at county crossing

The Humboldt County Board of Supervisors approved an application from Martin Marietta to install advanced warning signage, including solar amber beacons, on county right-of-way at an at-grade crossing used by truck traffic for a quarry on the Humboldt County side.

Ben, a county staff member, described the company’s request: "Martin Marietta is interested in installing some advanced warning signs on both sides of the road north and south of where they're crossing, to get to the quarrying operation that they have on Humboldt County side." He said the signs aim "to bring extra attention to that crossing for the rest of the public." Board members discussed whether allowing private signage in the right-of-way could set a precedent for advertising. One supervisor said he did not bring the request before the board of adjustment because "this is just warning the public," distinguishing the proposed truck-crossing signs from advertising placards.

Ben noted Martin Marietta would install and maintain the signs and provide insurance coverage: "This says Martin Marietta is gonna install it and maintain it." Supervisors also discussed the beacons themselves; Ben referenced a recent county installation to bring attention to a similar hazard, saying "the amber beacons that they're proposing that go on top of signs, we put one up very similar, by Linda Lisonbee place." The board approved the application by voice vote with no recorded opposition.

The board did not adopt a formal, written policy change during the meeting; members emphasized distinguishing safety warning signage from advertising signage when considering future requests. No timeline for installation was specified in the meeting record.

Action on the application allows Martin Marietta to proceed with sign installation subject to standard county right-of-way permitting requirements and the condition that the company install and maintain the equipment.
